Thanks
I'm going to go and buy an 8/3300mAh this week. The one shown in the link below...

It's quite heavy at 518grams, but the magi should cope with no probs. After all it is meant to be able to tow gliders etc...
I will let you know how I get on...
What power set-up are you flying yours on Greg?
